Biology of the unborn is something we to this day dont really know anything about, because its impossible to run studies etc in situ. Clearly they have a hyperactive cell-division thing going on, their hearts as I recall work differently because instead of routing blood via lungs which haven't yet started to function property, they instead route to the umbilical and oxygenate via their mother. Probably a very embryonic immune system thats waiting for that first big shot of infusions via mothers first post-birth feedings.

So chemicals that can sicken and kill adults rapidly are not going to be good for poor babies. I wonder if we can expect all these bubs to have much shorter life expectancies.. probably so.

Nothing more evil than this has been done in the history of the world - nothing.
